What can geckos eat other than insects?

In what I know, leopard geckos eat veggies. I hope that helps!

leopard geckos still eat insects. go with a crested gecko they can eat crested gecko diet, that is powder that you mix with water and they eat fruit and yogurt but mainly feed him the diet, and if you can try giving him a cricket or two every two weeks but its not nessesary, they're better than leopard geckos cause of their diet, and while a leopard gecko would sit and look pretty a crested gecko actually moves, their housing is usually cheaper because they're aborial and need a tall tank insted of a long one like a leopard gecko's. and rainforest tanks for cresteds look better than desert style tanks for leopard geckos. and cesteds come in more varieties including yellow with black spots if you like the leopard look, to me they are better to handle when you learn how to handle them than leopards, just observe tem in the tank and watch the pose they go into before they jump that way when you handle them you can know when to stop them and block their path before they jump, don't worry they take their sweet time in getting ready for a jump, but for safety handle them close to the floor and preferably over carpet hope this helps you
